Research Abstract

Ten healthy male Slc: Wistar rats were repeatedly injected (i.p.) with a chelating agent and iron. Five of 10 rats showed a malignant peritoneal mesothelioma, but no rats showed it in the control and the chelating agent administration group. The tumor cells were positively stained by Calretinin and CEA. The results of immunostaining and the findings by electron microscope indicated epithelial mesothelioma. In addition, immunostaining with 8-hydroxy-2-deoxyguanosine is a DNA oxidative damage marker was positive. Thus, the conventional theoriy was confirmed. The final analysis of trace elements including radium is ongoing.
